K(490) is the diffuse attenuation coefficient of seawater at 490 nm. It indicates the turbidity of the water column, how visible light in the blue- green region of the spectrum penetrates within the water column. It is directly related to the presence of scattering particles in the water column. K(490)=(z 90 ) -1 m -1 MODIS algorithm estimate K(490), from the blue-to- green band ratio of water- leaving radiance 22-April-2004 MODIS/Aqua
